HOW TO TELL EMISSION TYPE CALIFORNIA CA OR FEDERAL EMISSIONS 1999-2000 MAXIMA. NO OTHER YEARS MATTER FOR DETERMINING WHICH Y PIPE YOU NEED TO FIT YOUR CAR, JUST THE 1999 AND 2000. EASIEST WAY TO TELL:

1. LOOK UNDER DRIVERS SIDE OF CAR, ABOUT CENTER OF DRIVER DOOR.
2. LOOK FOR THE MAIN CONVERTER, ALL THE FED MODELS HAVE AN S PIPE WITH O2 BUNG IN THEM THAT IS ATTACHED TO REAR OF CONVERTER.
   THE CA 1999.5-2001 DO NOT HAVE THE O2 SENSOR AND S PIPE.
